A Novel Strategy for High‐Sensitivity Detection of Sulfadiazine Using Green Silicon Quantum Dots Based Fluorescent Molecularly Imprinted Sensors

Polymers for Advanced Technologies, Journal Year: 2025, Volume and Issue: 36(2)

Published: Feb. 1, 2025

ABSTRACT The issue of pharmaceutical residues in the environment has become increasingly severe, with detection sulfonamide antibiotics emerging as a research hotspot environmental monitoring. Herein, we present method for detecting sulfadiazine based on silicon quantum dots (SiQDs)‐based fluorescent molecularly imprinted sensor. SiQDs, synthesized using an aqueous phase method, exhibit remarkable properties, such broad excitation spectrum, tunable emission wavelengths, and high fluorescence stability, offering significant advantages detection. By integrating amino‐functionalized silica nanospheres (NH 2 ‐SiO ) tetraethyl orthosilicate, SiQDs were surface‐functionalized to construct SiQDs@NH @MIPs composite materials. modified polymers not only exhibited selectivity affinity target molecule SDZ, but also demonstrated excellent stability resistance interference complex environments. Experimental results revealed that sensor displayed strong linear correlation within concentration range 40–100 μmol·L −1 , limit 0.036 ng·mL demonstrating sensitivity selectivity. In real sample applications, recovery rate ranged from 97.88% 100.74%, relative standard deviation less than 5.37%. These findings emphasize wide potential applications this sensor, especially water quality monitoring, protection,

N-Doped Carbon Layer Encapsulated NiP_x for Photocatalytic Alcohol Oxidation Coupled Hydrogen Evolution on Ag–In–Zn–S Quantum Dots

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 24, 2025

The photocatalytic oxidation of alcohols to value-added chemicals with simultaneous hydrogen (H2) generation is a promising sustainable process that suffers from slow charge transfer and poor integration both reactions. Here, an NH2-containing Ni metal-organic framework (MOF) used as precursor for creating N-doped C layer encapsulated nickel phosphide (NiPx@NC), which effectively enhances the reaction coupling when modified on narrow-band-gap Ag-In-Zn-S quantum dots (AIZS QDs). resulting AIZS/NiPx@NC photocatalysts demonstrate high efficiency benzyl alcohol (BA) coupled H2 evolution, achieving H2/benzaldehyde production rates 9.66/5.67 mmol g-1 h-1, are 3.30 47.25 times higher than those pure AIZS QDs, respectively. Additionally, selectivity benzaldehyde enhanced 77.96%. also shows improved performance other organics, including 4-methoxybenzyl biomass-derived furfuryl alcohol. Photoelectrochemical transient photovoltage spectroscopy tests confirm increased effective surface charges efficiency, while electron paramagnetic resonance reveals carbon-centered radical pathway selective formation. DFT calculations suggest carbon proton adsorption sites BA NiPx@NC surface. This work highlights potential multifunction in developing carbon-based cocatalysts evolution.
